Final answer:
In Nevada, trafficking a controlled substance, specifically Schedule 1, of 4 grams or more but less than 14 grams, is classified as a category B felony, with marijuana included despite its legal status in some states.
Step-by-step explanation:
In Nevada, trafficking any controlled substance of 4 grams or more, but less than 14 grams is a category B felony. When it comes to Schedule 1 Substances, which are considered the most dangerous and have a high potential for abuse according to federal classifications, trafficking such substances is taken very seriously. Not only does this apply to substances like heroin or LSD but also to marijuana, which, despite being legal for recreational use in some states and for medicinal purposes in a majority of the country, is still a Schedule 1 drug under federal law. This dichotomy between state and federal regulations can lead to complex legal scenarios where individuals may be operating legally under their state's law but still face federal charges, including for possession, trafficking, or running dispensaries.
